In a previous post, I gave an introduction to the yahoo_fin package. The most updated version of the package includes new functionality allowing you to scrape live stock prices from Yahoo Finance (real-time). In this article, we’ll go through a couple ways of getting real-time data from Yahoo Finance for stocks, as well as how to pull cryptocurrency price information.
The get_live_price function
First, we just need to load the stock_info module from yahoo_fin.
# import stock_info module from yahoo_fin from yahoo_fin import stock_info as si
Then, obtaining the current price of a stock is as simple as one line of code:
# get live price of Apple
si.get_live_price("aapl")
# or Amazon
si.get_live_price("amzn")
# or any other ticker
si.get_live_price(ticker)
Note: Passing tickers is not case-sensitive (upper / lower / mixed doesn’t matter).
Getting live price with other quote data
The live stock price has also been added to the get_quote_table function, which pulls in additional information about the current trading day’s volume, bid / ask, 52-week range etc. — effectively all the attributes available on Yahoo’s quote page.
Just replace “aapl” with any other ticker you need.
# get quote table back as a data frame
si.get_quote_table("aapl", dict_result = False)
# or get it back as a dictionary (default)
si.get_quote_table("aapl")
How to get cryptocurrency prices
Also new in this yahoo_fin update is a function for getting the top cryptocurrency prices. These are updated frequently by Yahoo Finance (see this link).
Get back the prices on the top 100 (by market cap) cryptocurrencies by calling the get_top_cryptos function:
si.get_top_crypto()
How to get most active, biggest gainers / losers
The latest additions to yahoo_fin that we’ll show here are about getting data on the most actively traded stocks, as well what stocks have gained or lost the most during the trading session. Each of the functions below returns a pandas data frame with the (at most) top 100 stocks falling in each category (active / gainer / loser).
# get most active stocks on the day si.get_day_most_active() # get biggest gainers si.get_day_gainers() # get worst performers si.get_day_losers()
The data above is being pulled from these links:
Most Active: https://finance.yahoo.com/most-active
Top Gainers: https://finance.yahoo.com/gainers
Worst Performers: https://finance.yahoo.com/losers
